Abstract: This paper lists the common models for land-value evaluation and analyze some insufficiency points of them. The Kriging spatial analysis method in geostatistics is applied to urban land-value evaluation. This paper also introduces the base theories and methods of Kriging and expatiates the basic idea that applying Kriging to land-value evaluation. It explains carefully how to apply Kriging to land-evaluation and analyzing the feasibility of this model. Last this paper takes the residential land in Wuhan as an example to introduce the base land-value evaluation model based on Kriging and build the graph equivalence of Wuhan.
